Designed as an artist’s cooperative apartment building and the largest “studio” building in the city, the Hotel Des Artistes at 1 West 67th Street on the Upper West Side is one of NYC’s most famous and illustrious buildings. As one of a constellation of style stars in Ari Seth Cohen’s “Advanced Style” universe, former model, artist and muse to fashionistas of all ages Beatrix Ost is beloved for her perfect balance of creativity, confidence and cool. In a rare confluence of New York City fabulousness, the apartment Ost has shared with her husband, Ludwig Kuttner, since 2006 is on the market for $4 million–and the offbeat but ridiculously stylish space is every bit what we’d expect.

Among the building’s many famous residents have been dancer Isadora Duncan, playwright Noel Coward, writer Fannie Hurst, New York City Mayor John V. Lindsay, writer Alexander Woollcott, and artist Norman Rockwell. Artist Howard Chandler Christy, an early resident, painted murals for the building’s legendary restaurant, Café des Artistes.

The six-room duplex is filled with unique finds and brilliant finishes. The apartment has three exposures, 18-foot ceilings, tall windows, open city and Central Park views, three bedrooms plus an office area, two full baths, central air conditioning, a wraparound mezzanine, and tons of pre-war details.

When the couple first moved in, the duplex needed a complete overhaul, and they proceeded to undertake a year-long, $1 million renovation. The home has been covered in the Wall Street Journal among others for its eclectic style.

Unlike many older co-ops, the building offers a full menu of amenities including 24 hour concierge services, a live-in super, a swimming pool, a squash court, a fitness center, a roof garden and an elevator operator. Another perk: discounts at the Leopard restaurant on the ground floor. It might also be mentioned that Uma Thurman’s brother Mipam Thurman is among the agents representing this iconic Upper West Side property, making for a fine intersection of neighborhood royalty.
